At Rosemont Middle School, 55% of the student body purchases their lunch at school. 1. Write that as a ratio of part to whole.
55: 100 of the student body purchases lunch at school
2. What percent represents the student body who brings their lunch?
45%=0.45
3. How are both of these decimals related to the whole?

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
